MLB’s Fan Cave social media experiment will return for a third year next season. A spot inviting fans to apply for the "job" of watching all 2,430 regular-season MLB games inside the Greenwich Village Fan Cave debuts this week and will air on Fox’ telecasts of the World Series, which opens in either St. Louis or S.F. on Wednesday. More than 22,000 fans applied for the positions before this season, and the MLB Fan Cave began the season with a group of nine winners. This year’s visitors to the Fan Cave included nearly 200 active MLB players.

MLB said that its social media following has quadrupled since Opening Day to more than 1 million combined followers on Facebook, Twitter and Instagram, and the audience is younger (30 vs. 45) than the average avid MLB fan.
